Veterinarians in England had to "deflate" Trevor the dachshund after he blew up to three times his normal size. BBC News reports Fran Jennings rushed her 4-year-old pet to an emergency veterinary clinic after he bloated and began suffering breathing difficulty. "He'd blown up like a balloon," Jennings said. "He looked like a big fat seal. His whole body was like a blob," Jennings' daughter Jessica said. "We put him straight in the car and took him to the emergency vets and they had never seen anything quite like it," Jennings said. X-rays revealed air was being forced and trapped under Trevor's skin. He was diagnosed with sub-cutaneous emphysema, an abnormal collection of air under the skin."There were no external injuries that would explain how air had got under the skin, so we suspected that an internal injury to the airway could have been allowing the air in," veterinarian Michelle Coward told BBC News. "Every time he took a breath, some of the inhaled air escaped through a hole in his windpipe."A procedure was performed to stitch up a hole in the pup's windpipe, which relieved pressure and allowed the pup to "deflate" back to his previous size. Family members say Trevor is back to his normal self, "chasing chickens," and they wouldn't have him any other way.
